After resampling, the original flat layers are hidden and replaced by the 3D resampled tileset.

The tiles of the tileset are paged in and out on demand.

Therefore, a tileset is in principle not limited in size or extent.

A single layer or multiple selected layers can be removed, finally.

Example Data

For example, you can drag&drop a tileset data directory into the
viewer window:

Download the Hawaii or Fraenkische demo data
from the tileset section and drag&drop the HawaiiTileset or
FrankischeTileset directory into the viewer
window. Double-clicking on the layer brings the respective tileset
into view.
